The former Ugly Betty star, a New York native, was inducted into the Big Apple's Ride of Fame on Thursday (27Sep12) at a ribbon-cutting ceremony, where she unveiled a double-decker vehicle bearing her photograph and signature.

Tourism company Gray Line New York will now offer daily sightseeing tours on the bright red, open-top Williams bus.

The actress tweeted a photo of herself next to the 'mobile monument' with the caption, "Here's my own Nyc double decker bus (in the) Ride Of Fame. Proud New Yorker!"

Williams joins stars including Cyndi Lauper, Liza Minnelli, Marc Anthony, Whoopi Goldberg and Donald Trump, who have all been celebrated with their own buses and hailed as "exemplary New Yorkers" by Gray Line bosses.
